The state of the zero/span valves can also be controlled:
Manually from the analyzer’s front panel by using the SIGNAL I/O controls located under the DIAG Menu
(refer to Section 6.9.2),
By activating the instrument’s AutoCal feature (refer to Section 8.8),
Remotely by using the external digital control inputs (refer to Section 7.3.1.2 and Section 8.7.1), or
Remotely through the RS-232/485 serial I/O ports (refer to Appendix A-6 for the appropriate commands).
Sources of zero and span gas must be capable of supplying at least 650 cm3/min (maximum 2.5L/min. Both
supply lines should be vented outside of the analyzer’s enclosure. In order to prevent back-diffusion and
pressure effects, these vent lines should be between 2 and 10 meters in length.
